APPARATUS FOR CARBU RETING 'AIR.

SPECIFICATION forming part of Letters Patent n 735,011, dated July 2a, 1903.

Application filed May 27, 1902. Serial No; 109,141. (No model.)

To all whom itrmay concern:

Be it known that we, ASHBEL S. AVERY and CHARLES B. SMITH, citizens of the United States, residing at Manilla, in the county of Crawford and State of Iowa, have invented a new and useful Apparatus for Carbureting Air, 01 hich the following is a specification. Our object is to provide a new and useful apparatus .for making inflammatory gas adapted for all the purposes for which an illuminating and heat-producing gas can be utilized, to save time, labor, material, and expense in volatilizing liquid (preferably a light and cheap product or petroleum known as gasolene) and mingling air therewith, to promote safety and convenience in the making, controlling, purifying, drying, and

distributing gasto burners, and to automat ically govern the supply as required for any given number of burners and also to regulate the quality as well as the quantity.

Our invention consistsiu the construction, arrangement, and combination of elements and subcombinations,as hereinafter-set forth, pointed out in our claims, and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation showing all the parts connected as required for practical use in delivering gas to a main pipe for distribution or to a supply-pipe and burners connectod therewith. Parts are broken away to show interior construction. Fig. 2 is an enlarged vertical sectional View of one of the carburetors and shows an air-distributor in the bottom and a liquid'sprayer in the top.

* Fig. 3 is a transverse sectional view of a carbureter and an airdistributer in the bottom. Fig. 4 is an enlarged sectional view of the drier. Fig. 5 is an enlarged sectional view of the adj ustable float and pressure regulator. Fig. 6 is a detail View of the automatic cutoif mechanism connected with the bell of the gas-holder and the pipe that feeds air to the carburetors.

The numeral 10 designates an air-pump adapted to be connected with a gas'engine or other suitable motor by means of a belt, as indicated in Fig. 1 or in any other practical way.

A, B, and O are carburetors connected at their lower ends by pipes 12 and 13, as shown in Fig. 1. Each of those connecting-pipes has a cut-off valve 14 for closing communication between the carburetors. An air-distributer, preferably in the form of a chamber the bottom of each of the carburetors A, B,

and G. A pipe 17 extends from the air-pump 10 and has branches that extend into the airdistribnters 15 in the carburetors A B C, as shown in Fig. 2. The tubes 16 are closed at their free ends and perforated on their tops or sides for discharging jets of air into the liquid in which they'aro immersed. 'lheupper ends of the carburetors A B C are connected with each other by pipes 18 and 19, and each of those pipes is provided with an automatic chock-valve 20 and a cut-off valve 21 for regulating communication between the carburetors at their top portions.

When the tem per-atnre of the oil is changed by means of the coil 56 in the tank L and the Y burner 58 and distributed in the top of the carburetor A, the automatic valves 20 in the pipes 19 allow communication between the carburetors A, B, and O, and the cut-off valves 21 in the pipes 19 are open in the direction from A to B and B to C, and when the cut-off valve 2i, connected with the pipe 19 between the carburetors l3 and C, and the cut-01f valve in the pipe 44 are closed the automatic valve 20 makes the carburetor C inoperative, so that the carburetors A and [5 alone will supply the quantity of gas desired, and by then closing the cut-oil v'.-t'lves:3l on the pipes 19 between the cai'l'iuroters A and ll and the cut-oil valve -15 on the pipe 4-1 only the one carburetor A will be operative as required to supplya diminished quuutityol' gas whenever desired. The advantage oi thus combining the carburetors in an apparatus as a means of regulating temperature and regulating supply is therefore an important dosideratum in the art. I

When the three carburetors A, l5, and O are simultaneously operated, their products when mingled in the purifier ll will be of the same temper-aw re as produced by means of the temperature etfccted in the oil that is passed through the coil'56 in the tank L.

A supplytahl; D for storing gasoleue is connected with the carburetors A 15 (J as required for delivering liquid to them and also for returning surplus'liquid from the carb'nreters to the tank, as hereinafter set forth. A chamber 22 is connected with the tank D by a pipe 23 and with the center carburetor 5 B by-a pipe 2% for conveying oil from the tank to the carbureter B and from thence to the carburetors A and through the connecting-tubes 12 and 18. A heat 24% for regulating the passage of liquid from the tank D to the carburetor B. is mounted in the chamber 22' and provided with means for restricting the up and down motions of the float, as shown in Fig. or in anysuitable way as required for governing the-quantity of oil passed from the tankto the carburetors. A rod 25 is adjust ably connected with the chamher, and arcd 26, connectedwith the float, is pivotallycohnected with the lowerend of the rod 25. A lever 27 is fulcrumed to a fixed support 28, and fixed to the rod 26 and 29 is a valve pivotally connected With the lever and siidahly connected with the end of the pipe 23; through which fluid passes from the tank D into the chamber 22 matically regulating the feeding of liquid to the carburetors A,'B, and O. The lever 27 and the rod 26 being rigidly united ahd the rod pivotaily connected with the adjustable rod 25,"it is obvious the float and valve connected therewith are simultaneously operated as required to regulate the how of oilinto' the chamber 22. A gage 30, connected with each carburetor, shows the amount'of oil in each, and for equalizing the amount of oil in the three carbureters and returning any surplus of liquid therefrom to the tank I) a pump 31 is connected with the tank by a pipe and with a pipe-coupling chamher 38 by a pipe 3i, and the chamber 33 is connected with the carburetor O bya pipe 35 and with the carburetor A by a pipe 36 and the carburetor B bya pipe 37, as shown in Fig. 1 or in any suitable way, in such a manner that when a larger quantity of oil has been fed to the carburetors through means of a temperature-regulator and a sprayer, as hereinafter set forth, the surplus may be readily returned to the tank D.

A check-valve 38 in the pipe 32 normally revents liquid from passing to the pump 31 cm the tank D, but allows the pump to return liquid from the carburetors to the tank. A cut-oft valve'39 can be used for closing communication between the pump and the tan k D.

A cut-nit valve 40 in the pipe 34 closes communication between the pump 31 and the chamber 33, and a check-valve 41 in each of the pipes 35, 36, and 37 closes communication between the chamber 33 and the several carburetors A B C in'such a manner that oil can be pumped to and from the carburetors as required to maintain an equal supply of liquid in each carbureter.

as required for auto- I and top, is located in a plane above the carbureters, (or otherwise, as may suit best in different places,) has pipe extended down at one end, and is connected with the tops of the carburters A B G by apipe ti and branches 42, 43, and at, and each branch is provided with a cut-off value 45 as required to cut off communication with the separator whenever desired. Thegas that enters the bottom at one end of the separator passes in the serpentine passage. produced by the partitions c and passes out at the top of the other end through the pipe 46 into the drierJ, andauy surplus of valuable oil that may be in the gas or other objectionable matter will be precipitated and descend into the draining-tubes CZ, fixed in the bottom of the chamber, from whence it is drawn through a valve f.

In a plane above the separator H is located a drier-J, constructed as shown in Fig. e and connected with the separator H bya tube 46. It preferably has a concaved bottom, and in its lower portion is placed a perforated plate 47, and on top of the plate is placed mineral Wool or suitable drying material, and on top of the mineral wool is placed a perforated follower 48. The head or. top of the drier is fitted and fixed as shown or in any suitable Way as required to close the drier air-tight. A pipe 49 extends from the drier to a gasholder K, and a pipe 50 is connected with the drier J to be extended to a street-main for distributing gas to supply-pipes that may be connected therewith.

To control the passage of gas from the drier to the gas-holderK, a cut-cit valve 51 is connected with a pipe 49, a cut-off valve 52 with the pipe 50, leading to a main, as shown in Fig. l or in any suitable way, so that gas may be conveyed direct from the drier to a main or to a gas-holder at the \villot the operator.

To regulate the temperature of the gasolene in the carburetors A B C, a pipe 55 is connected with the tank I) and extended to a rotary pump F, and from thence to a coil 56 in a water-tank L, and a pipe 57 connected with the other end of the coil and extended into the top of the carburetor A and connccted with the sprayer 59, as shown in Fig.

2, so the liquid pumped into the coil and back into the carburetor will be subjected to the action of the water in the tank L. I To warm the water in the tank, a gas-burner 58 or other suitable heating device is located under the tank. In place of connecting the pipe 57 with the sprayer iu the carburetor A it may be connected with the tank I), as shown in Fig. 1, and the sprayer dispensed with.

The sprayer fixed to the pipe 57, as shown in Fig. 2 or in anysuitable form desired, facilitaies the mingling of the oil and air as require to produce inflammable Air passes from the carburetor A into the carburetors l3 and C through the pipes that connect them, and the air and oil mingled in the three carburetors passes through the pipes fixed in their tops into the pipe 42 and from thence into the condenser H through the pipe 47.

A thermometer 60, connected with the carbureter B, shows the temperature of the contents as required to direct the operation of the coil 56 in the water-tank L.

To convey gas direct from the gas-holder K, a service-pipe 61 is connected with the gasholder in a common way to extend upward-inside of the gas-holder. The pipe 49 also extends npin the gas-holder K, as shown in Fig. 6, and between the upper ends of the pipes 61 and 49 a float 62 is placed and concaved in its top surface and adapted to receive any condensation that may occurin the bell Kiand a flexible tube 63,conuected with the float and extended out at the lower end of the gas-holder,will carryoff such condensation. The service-pipe 61 is provided with a cut-off valve 64, that must be closed when the valve 51 in-the pipe 49 is closed and the valve 52 in the pipe 50 is opened for conveying gas direct from the drier J to a main or service-pipe.

To distribute air-pressure from the carburetersA B O to the tank D as required to facilitate circulation of liquid through the chamber 22 and the carbureters, a pipe 64, provided with avalve b, isconnected with the top portion of the tankD and the carbureter A, as shown in Fig. 1.

To automatically govern the introduction and circulation of air -in the carbureters A B C, the pipe 17is extended from the air-pump and connected with the-air-dis'tributers in the carbureters, as shownflin Fig. 2, and a valve-chamber 6G is connected with the pipeand provided with a vent 67. An arm 68 projects from the end of a three-way valve fitted in the chamber to. A lever 69 is fnlcrumed to the outside of the gas-holder K or other suitable support and provided with bridles 7 and 71 at its ends and connected with the arm 68 by means of a rod 72, pivoted to the end of the arm and extended down through the bridle 71. An arm 75 projects upward from the center of the lever 69 and carries a weight 76 at its end to impart sudden motion to the lever as required for operating the valve-arm G8 and opening and closing communication between the air-pump and carbureters. Stop devices 77, fixed to the rods 72 and 73 above and below the bridles and 71, contact with the ends of the lever as required to alternately press the ends of the levers up and down, so that when the arm 75 passesa perpendicular line the weight 76 will impart a sudden motion to the lever as required to actuate the arm 58 ot' the threeway valve fitted in the valve-chamber 66. In position shown in Fig. l the bell K is rising and lifting the bridle 71 and moving the weighted arm toward a perpendicular line, and the instant the center of gravity of the weight passes that line the lever will strike the stop 77 on the lower end of the rod 72 and pull down the arm 68 of the valve to In the practical operation of our invention. 1

oil is fed to the carbureters'A, B, and O and the quantity regulated by means of the automatic mechanism in the chamber 22. When it is desirable to change the temperature of the oil and air in the carbureters, oil is pumped into the coil 56 and subjected to the action of the water in the tank L to change the temperature of the contents of the carbureters by conveying oil from the coil into the carbureters to mingle with their contents.

perature. To regulate the quantity of gas that is required for ditferent numbers of burners at difle'rent times, each carburetor isindependently connected with the separator H, so that the supply is readily governed by means of the valves in the tubes 'thatrconnect the carburetors with the separator, from which the gas passes through the drier J and from thence direct to a street-main by a pipe 50 or first into the gas-holder and from thence to a service-pipe 61.

The gas thus produced is regulated in tem- 1 The supply of gas conveyed into the gas- I holder is automatically regulated by the automatic mechanism connected with the gasholder and the pipe 17 and valve 66, connected with the air-pu mp, and the carbureters A, B, and C. r
